Quoting Thomas M Goerger tmg@umn.edu:

We are currently running Dovecot v1.1.6 on our servers, and are contemplating an upgrade to 1.2, or 2.0 soon. We are wondering how many organizations are still running a 1.1 version of Dovecot, and if anyone has any thoughts on this transition.

Probably a lot running 1.1 still. I only upgraded late last year because I needed additional functionality (see below), otherwise I'd still be on 1.1 now.

Have you upgraded from 1.1 to 1.2? What are your experiences with this?

Yes, and it was painless. All the info you need is on the dovecot wiki.

Have you upgraded from 1.1 to 2.0 directly?

No.

What are your experiences this way? We are also running an environment with both mbox and maildir formats. How many of you are running similarly, or are running solely maildir or mbox?

We ran solely mbox with 1.1. The reason I upgrade to 1.2 was to be able to run primarily mbox, but also run a few maildir accounts for shared folders with per-user flags with easy time-based expiration (retention policy). So we just have a couple maildir accounts used exclusively as shared-folder accounts (with per-user-flags and auto-expiration of messages after a set rention period) and the rest are still mbox ( with no retention/expiration, no shared folders, etc)

If it wasn't for the desire to do the shared folders with expiration, we'd have stayed with 1.1 still.

We're just looking to gather information going forward, and anything you might be able to contribute would be very helpful.

It was a painless process for me. No problems.

We uprgaded on CentOS 5.x using RPM packages from atrpms.net, and going from dovecot-1.1.18-1_95.el5.x86_64.rpm to dovecot-1.2.4-0_99.el5.x86_64.rpm if that's any help. :)

Thanks!

Hi Tom,

We are running 1.1.x (http://atrpms.net/dist/el4/dovecot-1.1.x/), after a recent upgrade from 0.99 on a CentOS 4 system. The upgrade went flawlessly after reading the wiki, asking a couple of questions here and testing first with a test system.

Then I looked at 1.2. I saw there was some possible issues with our set up, so I went with the good old and tried 1.1.x instead.

So far 1.1.x is has performed beautiful, so if it is not broken, no reason to fix it.

Down the line, I'll plan to upgrade to 1.2.x , after 2.0.x is fully stable. Of course I'll need some time, no current projects in /dev/TODO and a good reason to change something that works just fine :-)
